To all-whom t may concemg Be it` known that I, MILLER REESE HUToHisoN, acitizen of the resident of Summit, in the have invented certain new and useful Improvements in Gearing, of which the following is a specification.

My present invention relates to certain improvements in a` mechanically actuated diaphragm horn and driving mechanism therefor, comprising a complete non-electrical outiit adapted for ready attachment to a vehicle with the horn in suitable position for signaling and the power connection 1n operative relation to the motor power of said vehicle or launch.

The devices shown herein are shown and described, but not specifically claimed in their present combination, in my prior application, Serial No. 373,946, of which the present ap lication is a division.

The out t comprises a horn adapted to be used either side up and preferably provided with a laterally tachment to the side of a suitable support on the vehicle. The power for driving the mechanically actuated means is transmitted through a fiexible shaft of any desired length, which receives power from any rotating part of the vehicle through the medium of a driving connection, preferably frictional, adapted to be thrown into and out of operative relation to the prime mover.

The specific form of friction pulley shown herein is peculiarly adapted for attachment to either side of a rotary driver to meet the exigencies of the particular location in which the device is to be used.

My present invention may be-more fully understood by the following detail description and claims when taken in connection the accompanying drawings, which- Figure l and Fig. 2 are side and front elevations of the-horn, portions of Fig. l being broken away to vertical section to show the relations of the diaphragm, the clamping section. ofthe case, and the rotary vibrator for' the diaphragm. Figs. '3 and 4 are respectively Vfront `and rear United States, vand a county of Union extending bracket for at-v elevations of a power connection `for Ithe horn, adapted to be applied to the motor or motive mechanism on whichever side of the Vvehicle or launch the horn may be mounted. F ig. 5 is a'section on the lineZ Z, Fig. 4. `ig. 6 is a detail of the shaft connection shown in Fig-5. n

v Fig. =l.shows certain characteristic features of the operating mechanism of the horn sufficient for present purposes. It will be understood that the details now shown maybe and preferably are such as shown in said application Serial No. 373,946. The operating mechanism comprises a cam 59, suitably supported in operative relation to a thrust member 70, secured upon the diaphragm 53. The structure of the latter may be such as described in my Patent' No. 883,643. The cam is rotated by flexible shaft 52 passing through 40, and secured in place by a screw sleeve 87. The case is formed with similar boss 84 in which an oil cup 83 isl screwed.- The bosses 88 and 84 are' similar and symmetrical, so that either one of them' is equally adapted for passage of the drive shaft or of the oil cup, according as the' device'is arranged one side up or the other side up 'in practical use'. The rear section of the case is formed with an annular clamping surface 14, adapted to cooperate with the front cover or resonator section, to clamp the peripheral portionof the diaphragm 53, by means of the bolts 41, 42, 43, extending through the clamping surfaces and through corresponding openings of the periphery ofl the diaphragm. 4'll`he front case is preferably parallel with the diaphragm and far enough away from it to permit maximum vibration of the diaphragm without engagement of the latter with the case. The case is formed with a central opening 6() preferably of large diameter so as to expose a large part vof the effectively vibrating part of the diaadapted to transmit `as a definite acoustic wave the large amount of power available the boss 88 in the casel i from the mechanically driven diaphragm.

The opening G0 is surrounded by an annular flange 64. The resonator 48 is secured to this flange either by spinning the metal against the outer wall thereof or by brazing, or preferably by both. The periphery of the front case 44 is preferably formed with a rearwardly extending annular flange 65 adapted to t over the rear section of the` case and protect the seams between the diaphragm and clamping surfaces. The quality of the note is improved and destructive -vibration and cutting action'of the diaphragm, which would result from direct contact'of vibratory elastic metals, is prevented'by washers or gaskets 53, 54, arranged on each side of the `diaphragm between it and the clamping faces on the front and rear sections of the case. These washers may bel of non-vibratory material., such as cork, wood, or hardened fiber, the material and the arrangement thereof being such that when clamped in place by the screwl bolts 41, 42, 43 a water tight joint is formed. As the open end of the horn is usually presented in the direction of movement of the vehicle or launch, it is desirable to have drain openings at 89, 90, so as to afford an outlet for water or small particles of dirt, which may find their way `through the openl end of the horn into the space between the diaphragm and the front wall 11.' By having two such drain holes, one at the top and the A other at the bottom of the case, there'will l l whichever side of the device happens to be downward when in use. The device 1s proalways be one of them in operative position,

vided with a bracket 49, adapted to be secured by bolts 51 to the side of an upright support 50, which in this case is shown as a section of the dash-board of an automobile.

As will be evident by comparing. Figs. 1 and 2, the resonator 48 is laterally flattened soi as to have a transverse major axis arranged vertically and preferably terminating in av bell, having a correspondingly flattenedI or oval outline. I have discovered that flattening of the resonator has the effect of spreading the sound in the direction in which the resonator is of smallest diameter and of limiting the spread in the direction in which the resonator is of greatest diameter. -This phenomenon renders the device particularly convenient for attachment to the side of a support, since the disposition of resonator' which is most advantageous acoustically, is the one which is most cornpact and most desirable physically.

It will be obvious from the above that if it is desired to shift the horn from the side of the dash-board indicated in Fig. 2 over y to the other side, it is only necessary to re- Verse the connection of the flexible shaft 52 and oil cup 83, and to turn the horn over so that the bracket 49 will project from the left hand Side thereof, instead of the right hand side. In either case, the resonator has its major axis in a vertical plane with the one or the other of the drain holes in position to afford an outlet from whichever p0rtion of the space between the diaphragm and front wall happens to be lowermost.

The power connection of the horn comprises an adjustable arrangement of great flexibility which is adapted for attachment in a great variety of situations met with in practice. This arrangement is shown in Figs. 3, 4, 5, and 6, wherein the shaft 52 is shown connected to a pulley 110, journaled in the hanger 111, which is adapted to be secured tojany desired support 112 adjacent arotating part of the engine, such as the fly wheel 113, lin such manner as to permit the pulley 110 to be thrown into and out of Contact with said fly wheel. In the specific form shown in the drawings, the base 114 is secured to the support 112 by screws 115, 116. This case is provided with a cylindrical pivot or projection 117, upon which the hanger 111 is mounted to swing, said cylindrical projection being formed with a screw thread 118 for engaging a nut 119 and washer-120. In the lower end of the hanger is journaled the hollow shaft 121. Upon the projecting end 122, of shaft 121, is secured the friction wheel 110 by means of a nut v123' and key 124. This shaft is provided with transverse pins 125, engaging a slot 126 in a coupling piece 127. Into the recess 128 in the rear end of said coupling is soldered the flexible shaft 52. The flexible projectingy cover for the flexible shaft is secured to a sleeve 129, which screws over a screw threaded boss 130 on the rear of the bearing.

The preferred means of swinging the hanger 111 to throw the friction wheel 4110 into and out of contact with the ily wheel 113 is an upward extension or lever arm 131. Thisarm may be integral with the hanger 111, but I prefer the construction shown in the drawings wherein the arm 131 is mounted upon the pivfot 117 and is coupled in fixed angular relation to the hanger 111 by means of the bolt' 132 and nut 133 passing through a registering hole in the integral projection 134 ofl hanger 111. The lever arm 131 is controlled by a retractile spring 135 acting to move said arm in one direction and the chain 136 acting tomove it in the other. I preferably arrange the spring 135 so that it will normally tend to hold the friction wheel 110 out ofI engagement with the fly wheel 113, the chain 136 being used to effect a positive movement of the friction wheel 110 in the opposite direction whenever it is desired to sound the horn, but this is not essential. In order that this driving mechanism may be applied at any most convenient point about the periphery of the fly wheel, the projection 134 is promeines vided with any desired number of bolt holes 137, 138, 139, 140, etc., so that the lever arm 131 may be secured in any desired angular relation to the hanger 111 by merely shifting the bolt 132. By these means it is possible to arrange matters so that a convenient support 112 may always be found and at the same time the direction of the pull of the chain 136 may be kept normal to the lever arm 131. The oil cup 1-11 supplies the bearing in 111 as indicated in Figs. -1 and 5.

I prefer to arrange brake slices 142, 143, on opposite sides of the pivot 117, so that the friction wheel 110 will be swung into contact therewith immediately upon being thrown out of contact with the fly wheel 113. By this arrangement the sound of the horn is stopped almost instantly upon release of the chain 136, thus avoiding a prolonged, dying away of the note of the horn. Under normal conditions, but one of the brake shoes will be used, but by providing two of them, the range of use of the device is increased, since it may be used on either side of the driver, either side up, facing either forwardly or rearwardly, and yet, however arranged, there will always be a brake shoe in operative relation thereto.

The periphery of the friction wheel 110 is formed with grooves 1103 and ribs 110", so that the ribs may come into close frictional contact with the surface of the fly wheel 113, and any lubricant or other foreign matter on such surface will be squeezed into the grooves 1102l at the point of such contact.

. Moreover, the liigh speed of the pulley will tend to throw ofi' such matter from the summit of the ribs by centrifugal force before it becomes suiiciently accumulated to'fill the grooves. 1t will be obvious that instead of the fly wheel 113, I may employ any suitable driving mechanism, it being or many purposes preferable that said member be operated by hand or by other means. 1While 1 have herein fully shown and described, andv have pointed out in the appended claims certain novel features of construction, arrangement, and operation which characterize my invention, it will be understood by those skilled in the art that Vvarious omissions, substitutions, and changes in the forms, proportions, sizes, and details of the device and of its operation, may be madev without departing from my invention.
